Specification of Letters Patent.

Patented May 15, 1906.

Application filed August 18.1905. Serial No. 274,759.

Be it known that l, FRANK \NALLACE Ler- DECKER, a citizen of the l nitcd States, vn-siding at Marietta, in the county of Washington and State of Ohio, have invented a new and useful Gage-(Jock, of which the following is a. specification.

This invention relates generally to gagecocks, and ntorc particularly to that class employed on stead-boilers for ascertaining the ievcl of the we. or therein.

The object of t' c invention is to simplify the construction and increase the efficiency and dumbilitv of such ap liances.

With the above and ot or objects in view, as will appear as the nature of the invention is better understood, the sonic consists in the novel construction and combination of parts of a gage-cock for, steam-boilers, as will be hercinaltcr fully desczibcd and claimed.

In the accompanying drawings, turning a part of this specification, and in which like characters of reference indicate corresponding parts Figure 1 is a view in vertical longitudinal section through one form of the invention. Fig. 2 is a, collective detail view of parts of the valve mechanisms employed in connection withthe ap liance shown n Fig. 1. Fig. 3 is a vertical longitudinal section through a modified form of the invention.

Referring to the drawings and to Figs. 1 and 2 thereof, 1 designates the body of the cock, which is provided with the usual extorior threads to engage a threaded opening in the boiler. At the inner or hoileren aging end of the body is arranged a cage 2, w ich is y and'is designed to house a ball-valve 3, that is adapted to engage a. seat 4 when the main valve-stern 5 is removed for any purpose, thus to prevent escape of steam and water through the cock. The outer or vnlve-stern-carrying end 6 of the body is extcriorly threaded and is engaged by an internall -threaded cap 7, which constitutes a stu g-box, the cap being provided with a. longitudinally-threaded orifice to receive the main valve-stern, whichhas combined with it, as usual, a handle or handwhcel 8. The body is provided with a chan1- her 9, intersecting which is a passage-way 10 for the escape of water or steam from the iler. Arranged within the chamber 9 and gagcd by a balhvolve 13, that norm all f closes exit through the possagc-way and is raid to its scat bythc inner end of the main valve- SHEER} which is concaved to conform to the shape of the valve. The chamber. also houses a cage 14, that carries spaced lugs 15, the outer surfaces of which are flattened in order to present escape-passages 16 to permit the water to pass tlnou h a, m pic 17, that is combined with the b0 y of the cock in the usual manner.

Arranged within the passage-way is a twisted valve-stem 18, which is adapted to be rapidly turned or rotated by the passage of water or steam through the passage-way 10, and thus keep the letter free iom any accumulation of sediments or the like.

One of the features of the resent invention resides in dispensing wit the ordinary sterling-box, such as is gener ally errployed, and in making the ca 7 subseive this function, to effect which t e chamber in the cap that'receives the terminal 6 is of considerable depth and houses the packing 19, which may be of any suitable substance suited for the purpose, preferably asbestos. When the cap 1S seated, this aching is forced against the outer end 6 of t 0 body, and thus com resses it around the main valve-stem and e sets a steam and water tight juncture between the par ts, that portionof the stem which enga. es the packing being devoid of threads, so t at no cutting of the packing will ensue. A portion also of the opening in the cap that receives the main valve-stem is also devoid of threads in order that the latter may have requisite movement to permit the valve 13 to move away from the seat when the level of the water is to be ascertained. When the cap 19 is secured to its seat, the acking will engage with the ca 0 14, and thus old it positively within the c amber.

In the form of the invention shown in Fig 3 the only difference in construction is that the reversible valve-seat 12 and cage 14 are dispensed with, and the valve 16 enga cs 9. seat 20, formed by the shoulder 21 o the chamber 9.

From the foregoing description it will be seen that although the improvements herein defined are sim is in character they will be thorou hly e eetive for the purposes designed an will result in the provision of a gage-cock that will withstand wear and will not be liable to become doi'angod from longhot", a. 'ball-valw to onga'go tho soot, :1 ('ago continued use.
